Hi
I have a problem with jeep Cherokee 4lt 1998 no spark, I don't have the ignition circuit diagram so I cant track/test the circuit, the ignition coil has been replaced I have monitored the pick up on the distributor seems to be ok but I dont know if there is some fancy immobilizer issue any help appreciated
Thanks
Neil
